Longruner 5X Geared Stepper Motor 28byj 48 Uln2003 5v Stepper Motor Uln2003 Driver Board Compatible with ArduinoIDE (with Wire)

Updated: br>This is my very first stepper motor, which I built 20 years ago outside of college: )br>Here is a link to more technical information. While some examples show you how to connect power from the Arduino itself, others show you how to use a separate PS for these motors.
I made 2 motors that run on a single loop with a count down and "if(t?lay==0) do one step and
I made 2 motors that run on a% " logic. It takes 4096 steps to turn 360 degrees, and it takes a long time because each step is delayed by at least 31 microseconds. The motor would not move if the step cycle was shorter; however, I believe you can do gradual speedup once in motion, which I did not try. br>One thing I noticed, and I'll look into it more later, is that while running both motors, my PS became extremely hot. If you read my e-mail, you'll notice that I'm not the only one who think It was drawing almost 1 amp, according to my cheapo meter (surely my good one is in the car). PS kept cutting out, and my meter was powered by the same PS as the circuit, so readings were inconsistent. I looked for shorts but couldn't find any. Overall, for $2 per motor and driver board, as well as a few jumpers (almost enough for two motor connections), it's a good deal. I'm not sure if there's a better option that would save me money on a battery while also allowing me to move faster; the boards themselves appear to be a little crude, but two out of two have worked so far. In any case, this is a great tool for project work, learning, and prototyping. I'm hoping to persuade my 11-year-old to try his hand at making a working clock, but he'd rather play video games:.

With a 5V power supply from Arduino Uno, it has a lot of torque, and my finger can't stop it from spinning. It rotates at a rate of approximately 3V as well, but with much less torque. When using 3, my fingers are able to stop the rotation. Power supply of 3 volts It is very simple to set up. Look up "Arduino - Programming" in the search engine. For more information on setting it up with Arduino code, see "StepperUnipolar. " It has a 5mm shaft and consumes approximately 160mA at 5v. This is only for your benefit.

  Great product that is simple to use (plug and play). br>br>Great product that is simple to use (plug and play). There are no issues with precision. For my purposes, it's fast enough. br>br>I was also impressed by the packaging it came in. Any assistance with organization is greatly appreciated as an amateur roboticist. br>br>I can't say I'm happy with the price.

There's not a whole lot to say here - These are generic stepper motors that can be purchased on the internet from Chinese vendors. When I bought them on Amazon, the vendor I bought them from offered them at a reasonable price. There are no issues. Good value for the money, but don't expect high quality for the price.

These were used to create a computerized focus system for my telescope. To get good stepping without missing any steps, keep it around 75 parts per million. 250 ppm is too high, 125 is fine, but 75 ppm at full step worked perfectly for me. Without a doubt, it is well worth the money.

It is a good deal. These are being used in my computer science class for an Arduino project. This is a nice stepper motor set for a reasonable price (approximately $2). 75 dollars per set of motor and board. It's a plus if there's a storage container. I've previously purchased other Longrunner parts, such as servos and motors, and they've never let me down.

These motors are actually quite good and arrived exactly as described; I only docked a star because they didn't all rotate as smoothly as I had hoped.
